I have a related question as a current Leaf driver (lease) and considering a number of EVs or PHEVs. I would LOVE a programmable speed limiter (see https://en.wikipedia.org/wiki/Speed_limiter, scroll down to Programmable). That way when I drive many very curvy roads where I live where the speed limit is actually right on (for a Leaf's cornering ability or even a sports car because of limited visibility due to hills and trees with almost no shoulder), I could quickly set a limit to 35, 40, or 45 as the case may be, and let my foot off the pedal for strong regenerative braking but otherwise never have to look at the speedometer to make sure I'm not speeding.
Why is the only available on European cars but not the Bolt, Volt, Leaf, etc.? (Note: these limits are always defeatable simply by flooring it)
